I have a feeling that would pick up noise

Especially with that makeshift antenna hanging 💀
AmberPrince@kbin.social 11 months ago
The antenna looking piece of wire is the ground so it doesn't matter if it picks up anything.
bstix@feddit.dk 11 months ago
That’s the ground. It’s probably not an issue.

If the connections are solid it wouldn’t pick up any more noise than a 6.5mm to RCA adaptor would have. Any jiggle to the cable would result in popping or cracking though, depending on the configuration could be quite jarring.
DontRedditMyLemmy@lemmy.world 11 months ago
I think it does act like an antenna a little, so some noise is to be expected. Might be easy to attenuate that band though.
PM_Your_Nudes_Please@lemmy.world 11 months ago
No more than a standard connection. Every cable inherently acts as an antenna, so that’s why we try to avoid running them parallel to power lines and other things that would give off audible interference. If you actually want to reject interference, you’d need a balanced signal. Regular RCA and 1/4” are both unbalanced, so they’ll both pick up interference regardless of how they’re tied together.
When dealing with unbalanced cable, the most important part is making sure your signal to noise ratio is good. If you can get a hot enough signal that your gain can be lowered, you may be able to reduce the interference completely below your noise floor. Of course there are arguments against this (like how running things that hot could potentially mean you’re clipping your outputs, which introduces a whole host of other issues) but as a general rule, you want your gain to be as low as possible, so you can reduce the amount of background interference and noise you’re picking up.

I’m still very surprised that the most rudimentary of antenna can transmit and pick up signals acceptably. Like everything else in reality, I imagined that it’d have TONS of noise but somehow it’s all still audible.

Insulating tape on the signal wires, then foil tucked around that ground wire.
FlyingSquid@lemmy.world 11 months ago
You can order an adapter for like a dollar on multiple websites. I mean yeah, there’s no Radio Shack anymore, but this seems unnecessary.
I_Miss_Daniel@lemmy.world 11 months ago
I think this is more for that time you’re at a gig and realise you’re missing the adapter.
FlyingSquid@lemmy.world 11 months ago
That does make sense, although it would be weird to go to a gig and not have a 1/4" to RCA adapter but happen to have large-gauge copper wire.
pete_the_cat@lemmy.world 11 months ago
… And you just happen to have a piece of like 12 or 14 AWG copper wire on hand?

Overnight? Do you deliver overminute?
PM_Your_Nudes_Please@lemmy.world 11 months ago
You don’t always have the luxury of time though. I work in entertainment, and I’ve definitely scrapped adapters together in a pinch. When you have a show starting in 15 minutes and a musician rolls up with some bespoke gear with weird connections, your only real choice is to bodge something together and make it work.
Nothing quite like seeing five adapters chained together, to go from stereo RCA to TRS 1/8” to TRS 1/4” to dual TS 1/4”, to XLR… All because you didn’t have a direct box that went straight from RCA to XLR, because another musician walked off with it after their show wrapped up at 2AM last night.
sfgifz@lemmy.world 11 months ago
And how much is the delivery fee?
pete_the_cat@lemmy.world 11 months ago
Apparently there is at least one RadioShack open. I saw a dude post a video on YouTube about one he found in Wyoming.
Buffaloaf@lemmy.world 11 months ago
There’s one in Afton, Wy if that’s what you’re talking about. It has a giant “We Are Open!” sign that reminds me of Clerks

As long as whatever is on the other end doesn’t reproduce anything at 60Hz or does so with a lot of loss and there are no heavy vibrations closeby (such as the speakers themselves), it should be fine.
DontRedditMyLemmy@lemmy.world 11 months ago
Why 60 Hz? Doesn’t the frequency response of this antenna depend on the length/shape?
stoicmaverick@lemmy.world 11 months ago
Also the ever present buzz of the 50-60hz power all around you all the time depending on where you live.
Aceticon@lemmy.world 11 months ago
It’s the one part of the radio spectrum that’s also in the hearing range hence induced currents from it can be heard in an analog audio system and which would have a pretty decent amount of energy inside a building because it’s being emitted pretty much all around by the mains power wires.
That said, you’re right that depending on the length and shape those wire might not be a very good antenna for that frequency. Independently of that, I doubt there’s enough energy around to directly affect speakers, but it might be enough if that wire goes to an amplifier and only afterwards to the speakes.
That said, I’m from Digital Systems rather than Telecomms or Audio so take what I say on this as a semi-informed guess.
random_character_a@lemmy.world 11 months ago
It’s not stupid if it works. I can even see some artistry in that.
Prunebutt@feddit.de 11 months ago
Depends on your definition of “works”. Do you want stabilityin your sound?
random_character_a@lemmy.world 11 months ago
Depends on what we’re playing.There are genres where nobody notices, nor gives a shit.
mriormro@lemmy.world 11 months ago
A body with one kidney works. I still want to keep my second kidney.
Just because something works doesn’t mean it isn’t stupid.
Ferris@infosec.pub 11 months ago
i choose to interpret this as you thinking kidneys are stupid.
